new equipment the traditional method for dealing with these situations is to have new conduit runs trenched or bored at great expense and inconvenience or continue to operate with a time-consuming manual procedure but does installing a new conduit run prevent line condensation or corroding wires from recurring will it give you the freedom to expand your system with more sensors and controls in the future we recommend installing a system that handles your current needs and enables future expansion without the cost or inconvenience of disturbing your ongoing operations wireless is an ideal solution for retrofitting systems where conduit runs are problematic and expensive wireless tank farm monitoring in harsh conditions tank farms need to continually monitor various parameters including temperature pressure flow ph conductivity or water levels for tank locations not wired for power or data transfer a wireless sensor network can gather the tank data and transmit it to a central control location for analysis and logging tank fill levels are monitored continuously so that materials are maintained at a specific quantity because these tanks are slowly filled or depleted ultrasonic sensors can be used to measure the tank levels without false readings or tank wall interference alarms or setpoints can be announced with a visual alarm tied to a discrete output remote sensor readings can be forwarded to a host system for data tracking sending e-mail alerts or to trigger specific events such as refilling the tank monitoring motor temperatures reduces downtime if failing motors can be detected before they shut down,down time and machine damage can be minimized a field transmitter equipped with a thermocouple or rtd can collect temperature readings to monitor the environmental conditions near motors or bearings it can be mounted in a fixed position or on a moving device for mobile monitoring transmitters can also be installed to monitor vibration and temperature the sensor data is sent to a gateway installed in a central control location when predetermined temperature levels are detected the gateway can activate a visual or audible alarm alerting personnel that maintenance is required with this information maintenance personnel can more accurately predict failure based on performance indicators ,and service the motors to minimize downtime and damage wireless tank monitoring and fill level management waste water treatment plants and tank farms need to continually monitor various parameters including temperature pressure flow ph conductivity and water levels in most wastewater or tank farm installations the locations are not wired for power or data transfers battery-powered field transmitters can be used to precisely monitor critical holding tank levels sending data to your control center landfill methane reclamation and flare stack gas monitoring for regulatory compliance to meet governmental regulations landfill managers need to accurately monitor methane gas production removal venting and burning the ability to efficiently measure and collect data is an issue not only of resource management but also of compliance and accountability to governing organizations knowledge of both methane flow and temperature at the flare stack can define when ch4 is being emitted to the atmosphere because releasing methane could be a breach of the operator s license an operator could be fined or forced in the future to purchase carbon credits to accurately determine methane production levels and flow a pressure transducer can detect both pressure and vacuum present within the methane production system thermocouples connected to wireless field devices are used to accurately detect the heat of an active flame to verify that the combustion of methane is ongoing logically if the meter is indicating a methane flow and the temperature at the flare stack is high the operator is in compliance if the meter indicates methane flow and the temperature is low the operator is not in compliance pressure transducers and the temperature sensors collect the data and wirelessly transmit it back to a host system for logging and analysis to comply with local state and federal regulations monitoring multiple parameters on rotating equipment a bottling plant monitors the level pressure,and temperature inside each rotary filler to accurately determine when to activate inflow into the rotary filler to wirelessly monitor and report level pressure and temperatures in the rotary fillers,each filler is equipped with a battery-powered field node connected to a level probe a pressure transmitter and a thermistor field units send data back to the wireless gateway that is mounted near the rotary filler inflow controls and regulates when the inflow to the rotary tanks is activated.wireless systems eliminate the need for data and power wires on moving assemblies wireless monitoring retrofit to meet new regulations new regulations in a pharmaceutical production facility stipulate that liquid level of all fluids must be closely monitored and logged field sensors quickly and easily facilitate these monitoring requirements without new construction and wiring sensor data is sent back to the wireless gateway device where data is logged and alerts can be sent when fluid levels reach critical levels.
